I have 1 RODC currently in site A, now I would like to add in another Writable DC into site A and then when new writable DC is up then I will demote the RODC.

So Im wondering can I add RODC and Writable DC in the same AD site? Will there be any authentication issue or conflict occur?

Thank you.

    Hi,

    You can have a RODC and Writable DC in the same site, authentication requests can be serviced by either DC. If there is a write request, the request will be serviced by the writable DC. The netlogon DsGetDcName function is used to find a suitable writable DC using the DS_WRITABLE_FLAG.

    Gary.
